Introduction: Evidence points toward the early life being crucial for preventing nutrition-related diseases. As promotion of healthier food preferences in toddlerhood and preschool age might still modulate the trajectories of disease risk, understanding diet in these age groups is necessary. The objective was to analyze food consumption and diet quality of 1-5-year-old children living in Germany in relation to age and sex.

- The German version of GloboDiet, a software for assessing dietary recalls, was updated and needed verification through validation before use in a national study.
- A study involving 109 participants compared 24-hour diet recalls from GloboDiet with urine samples to validate protein and potassium intake using various statistical methods.
- Results indicated that while protein intake estimates were valid, potassium intake estimates were inconsistent, suggesting the dietary recalls might underestimate actual potassium intake despite showing good agreement with urine sample data.
The aim of the study was to analyze the energy and macronutrient intake over the course of the day of selected population groups in Germany defined by sex, age, BMI, SES, and diet quality. The study was based on food consumption data from the German National Nutrition Survey II (2005-2007) assessed by two 4-day dietary weighing records of 662 women and men aged between 18 and 80 years. Energy and macronutrient intake were calculated using the German Nutrient Database 3.
